BOM warns of more severe thunderstorms to come

SEVERE thunderstorms for large areas of NSW due to a deep low pressure trough moving through the state, is being predicted by the Bureau of Meterology.

BOM Acting New South Wales Regional Director, Mr Stephen Lellyett, said there was a high likelihood of severe thunderstorms about the western slopes and plains today with storms also possible in surrounding areas.

Severe thunderstorms will contract to the north east of NSW tomorrow.

"The main impacts are likely to be damaging wind gusts, large hail and localised heavy rainfall. We're closely monitoring the system and will issue warnings as the situation develops," he said.

"Storm season is already well underway, and storms have been quite widespread over the past week in New South Wales."

Mr Lellyett said that more storm activity was expected over the coming days and months.

"The majority of storms in NSW occur between November and March, and despite strong El Niño conditions, this year will be no exception for severe thunderstorms affecting the state," he said.

NSW SES Commission Adam Dent reminded communities to be prepared.

"With timely and appropriate preparation, some of this damage could have been prevented," he said.

"As severe storms are likely in many parts of the state tomorrow, it is important people prepare their homes and businesses now to minimise damage and keep themselves, and their families, safer.
